Juliana Roubion 4 CC X0 AXS Reserve evo Exclusive Complete Mountain Bike – Women’s 2024

The Juliana Roubion 4 CC X0 AXS Reserve evo Exclusive Complete Mountain Bike is poetry in bike form, if poetry were a bit gnarlier. Slam poetry maybe? With rocks and roots and high speed hoots. Juliana spared no expense with this bike, festooning their best CC carbon frame with the absolute tops in components: everything is big, light, and utterly bombproof. This build features hard-stopping SRAM Code Silver Stealth brakes and the incredible SRAM X0 Eagle AXS Transmission drivetrain, a revolutionary design which ditches your trusty derailleur hanger to mount directly to the frame. The carbon Reserve wheels share the frame’s lifetime guarantee, too. From DH shuttle runs to all-day epics in the backcountry, this Roubion is raring to go. There is no more capable bike!

Carbon CC Frame
–
CC denotes Juliana's highest grade carbon fiber frames. Use of the very best materials in the composite results in the lightest, best handling bikes.

Travel
–
160mm Front / 150mm Rear

Wheel Size
–
Sizes S-M: Mixed Wheel (29" Front / 27.5" Rear), Size XS: 27.5"

Lower-Link Mounted VPP® Suspension
–
VPP is based on the patented principle of having two short links rotating in opposite directions. This system provides huge design flexibility, allowing Juliana to manipulate shock rates to the intended purpose and character of each model; from short travel endurance bikes to World Championship winning DH machines. This redesign mounts the shock lower on the bike, making for an even better ride quality.

Proportional Chainstay Lengths
–
With rear ends that match the size range, this bike's geo and ride quality is the same for all riders.
